According to Celcom, VoLTE allows users to have High Definition (HD) voice quality and a much faster call set up time. However, Celcom VoLTE is not available for all phones just yet.
For now, the feature is only available to iPhone 7 up to iPhone 11 Pro Max and users must have at least iOS 13.3 installed in their iPhone. Nevertheless, Celcom is already committed to extend the VoLTE support to other smartphones and devices very soon. Meanwhile, do also note that Celcom VoLTE is currently available only to Celcom Mobile Postpaid customers. For further details, do check out Celcom’s official website right here. (Source: Celcom.)
